Customer Testimonials

“Not many other manufacturing facilities would prioritize a job with a volume this low. They treated us as if we were a long-time customer bringing in high-volume business.”
Manufacturing Engineer
1X Technologies
“We didn’t have time or budget for short-run molded prototypes. STEP technology let us skip tooling and still test a functional, high-fidelity part.”
Mechanical Engineer
NOVO
Fathom understands aerospace requirements, from material traceability to process control, and their engineering support helped us refine our profile for better strength-to-weight performance. Fathom’s expertise has been a real asset to our program.”
Mechanical Engineer
Tier 1 Defense Contractor
“Working with Fathom has made our purchasing process for 3D-printed components much easier. Their team is consistently fast, clear, and reliable — which matters a lot in medical, where timelines and documentation can get complicated. They turn around quotes quickly, communicate openly about lead times, and deliver parts that meet the exact specifications our engineering team requires. Fathom has saved us countless hours coordinating between suppliers, and they’ve become our go-to partner for rapid prototypes and low-volume builds.”
Senior Buyer
Medical Device Manufacturer
“Fathom has been a reliable partner for our subsystem assemblies. Their team consistently delivers parts that align correctly and drop into our builds without rework. They’re quick to flag design issues and offer practical fixes, which has saved us a lot of engineering time. Their ability to move fast on prototypes and scale into small-batch production makes them one of our go-to partners over the years and they’ve been able to grow with us.”
